Jury selection began Monday in the retrial of a Daly City man convicted of murdering his wife in 2006, a prosecutor said.

The effort to choose the jury that will decide whether Quincy Norton, 36, is guilty of stabbing Tamika Mack Norton started with juror hardship, assistant district attorney Karen Guidotti said. Potential members of the panel can be dismissed if they show that being on the jury would, for example, hurt their ability to make a living.

Guidotti said jury selection will likely take at least two more weeks and the trial itself could last a month and a half.

Norton was granted a new trial in May 2009 when it came to light that his original defense attorney had failed to have a knife, which may be the weapon used in the killing, tested by an independent expert. Defense attorney Lisa Maguire is expected to argue that the knife was used by Quincy Norton’s longtime girlfriend to murder his wife on July 22, 2009.

The Nortons had a turbulent relationship, which included previous domestic violence allegations and the longtime involvement of Quincy Norton with girlfriend Anitra Johnson. Maguire has said testing of the knife rules out her client and points to Johnson as the killer.

During the first trial, the prosecution argued that Quincy Norton attacked his wife in their Daly City home after she announced her plans to divorce him. The couple’s young sons, who were home at the time, testified to hearing their mother scream and seeing their father at home the day of the killing.

In the days after the killing, Norton dropped off his two sons, who were 8 and 9 years old at the time, with family members and disappeared. He was arrested in San Jose about a month after the killing and was later charged with murder. A jury convicted him in May 2008.

Norton’s new trial began last month, and attorneys have already gone through dozens of pretrial motions. Some of the most important have dealt with what evidence can be shown to the jury.

Deputy district attorney Al Giannini was granted the right to include in his case evidence of previous domestic violence in the Norton household. Maguire was allowed to introduce the DNA evidence that she claims shows Johnson is the killer.

Norton is being held without bail. Jury selection is expected to continue today in San Mateo County Superior Court.

Gangs were likely involved in the string of arson attacks, police said, and they come amid mounting concerns in Sweden about gang-related violence. More than 40 people were shot and killed in the Nordic country last year, and the prime minister said in January that he was not ruling out a military response to gang activity.

A rooftop camera recorded the silver Ford Fiesta driving past Parliament and suddenly veering sharply to the left, striking cyclists waiting at a set of lights, then crossing the road and crashing into a barrier outside Parliament.
